WALTER B. HAVENS, OF HARTFORD CITY, INDIANA.

CORN-HUSKING APPARATUS.

To all 'whom it may concern:

Be it known that I, WALTER B. I-IAvENs, a citizen of the United States,residing at Hartford City, in the county of Blackford and State ofIndia-na, have invented certain new and useful Improvements inCorn-Husking Apparatus, of which the following is a specication.

This invention relates to corn-husking apparatus, and has for its objectto provide an improved apparatus which removes the ears from the stalksand strips the husks from the ears, and also chops up the stalks for useas fodder.

A further object of the invention is to provide an apparatus of thiskind which is simple in construction, and inexpensive to operate.

The invention also aims to provide a pair of combined snapping andhusking rollers, and improved means for carrying the stalks to theformer, and the several ears to the latter.

The invention is illustrated in the accompanying drawings in which`Figure 1 is a side elevation, and Fig. 2 a plan view thereof. Fig. 3 isa vertical seetion on line 3-3 of Fig. 1., the snapping and huskingrollers being shown broken away. Fig. 4 is a sectional detail on theline ehe of Fig. 1. Fig. 5 is a sectional detail of the husking portionof the rollers and the coperating stripper comb hereinafter' referredto.

In the drawings 5 denotes the supporting frame of the apparatus. At thetop of said frame, at one end thereof, is a feed-table 6 on which thestalks to be operated on are placed. The feed-table projects from oneside of the supportingframe, and has means for straighterung out thestalks and carrying them buttends forward to the snapping and huskingrollers. Such means comprises a pair of suitably spaced parallelextending screw conveyers 7 mounted in slots S in the table, andprojecting above the same a proper distance so` that they can take holdof the stalks. At the outer edge of the table is an inclined board 9 tohold the stalks thereon, and near said end of the table are blocks 10for directing the stalks to the conveyers. These blocks are locatedabove the conveyers and set close thereto, and have beveled front ends11. The blocks are carried by bars 12 secured to the supporting frame bybolts 13 passing through slots 14 in the bars. By slotting the bars asstated, the blocks 10 can Specification of Letters Patent.

be set closer to or farther away from the endboard 9 according to thequantity of stalks on the table. The stalks are dumped on the table, andare directed by the inclined board 9, as well as by the beveled portion11 of the blocks 10, to the conveyers. For the purpose of evening up thebutt-ends of the stalks in their travel across the ta ble I locate anupright board 9a at the rear end of the table. This board is set so asto converge toward the inner or discharge ends of the conveyers, byreason of which the butt-ends of the stalks are evened up when they comein contact with the board and are carried along the same. The convey'ers7 are so located with respect to the snap ing and husking rollers thatthe stalks are t rawn between the latter when they reach the ends of theconveyers. Any stalks missing the rollers drop on the horizontal portionof an endless belt 15 traveling toward the rollers, and armed withiingers 15a which catch the stalks and push them between the rollers.rihe belt is located a short distance below the inner edge of the table,and it travels through a trough 16 which prevents the stalks fromdropping off the belt.

The means for snapping the ears off the stalks and removing the husksfrom the ears are a pair of upright rollers 17 journaled in suitablebearings 17a on the supporting frame. The rollers are inclined towardthe rear end of the apparatus, and near their upper ends they have aroughened or corrugated surface 18. This portion of the rollers acts tosnap the ears oif the stalks. The lower ends of the rollers are armedwith spikes 19, and this part of the rollers acts on the severed ears toremove the husks therefrom. parts of the rollers is a plain portion 20which is for a purpose to be hereinafter described.

The belt 15 )asses over guide-pulleys 21 at the ends of t 1e horizontalportion thereof, and over a guide-pulley 22 below the same. Theguide-pulleys 21 are mounted at the ends of the trough 16. One of thepulleys 21 is located close to the upper end of the snapping and huskingroller, and the belt travels over said pulley and then downward alonOrsaid rollers in close proximity thereto, and parallel to their axis, sothat the severed ears are forced against the spiked portion of therollers and the husks torn oli'.

Between the roughened and spiked 9 The bearings 17 a of the snapping andhusking rollers are made yielding to permit different sizes of stalks topass therebetween by means of springs 17b which press behind thebearings, the latter being slidably mounted in suitable guide-frames atthe top of ther supporting-frame of the machine. On the -iournals of therollers are spur-gears 22 which mesh. The teeth of said gears aresufficiently deep to permit the yielding movement of the rollers. One ofsaid spurgears is formed with a bevel gear 23 which meshes with a bevelgear 24 on a shaft 25 extending transversely and at right angles to theaxis of the rollers. This shaft is geared to the main drive-shaft 26 ofthe apparatus. On the shaft 25, immediately behind the snapping andhusking rollers, is mounted a cutter for chopping up the stalks asrtheyissue from the rollers after the ears have been torn off. The cuttercomprises two or more blades 27 secured to and extending radially fromthe shaft 25. The length of each blade is about the same as the lengthof the roughened portions 18 of the rollers. The blades rotate with theshaft 25 and travel past a stationary shear-blade 28 located close toone of the rollers. The stalks as they issue from the rollers travelpast this shear-blade, and are chopped up into small pieces for use asfodder by the rotating cutter.

Behind the spiked or husking portion 19 of the rollers are located combsfor removing the husks therefrom if they have a tendency to wrap orstick to the rollers which is often the case when the husks are dam Acomb is provided for each roller. ne of the combs may be formed bycontinuing the shear-blade 28 so as to extend along the husking portionof one of the rollers parallel thereto and arming said extension withteeth 28a which approach said roller tangentially and enter between itsspikes 19. The comb for the other roller is a bar 28h extending parallelto the husking portion of the roller and armed with teeth 28C arrangedin the same manner as the teeth 28a. The bar 28b may be secured to thesupporting frame of the apparatus in any suitable manner.

At the lower end of the snapping and husking rollers is a conveyer 29which carries the husked ears away. The chopped up stalks drop on aconveyer 8O which dumps them on the ground or into asuitable-receptacle.

The following gearing is employed for driving the various parts of theapparatus herein described: On the shaft 31 of the pulley 22 is a pulley32 which is connected y a belt 38 with a pulley 34 on the maindrive-shaft 26. The drive shaft 35 of the conveyer 30 is fitted with apulley 36 which is connected by a belt 87 with a pulley 38 on the shaft31.

pulley 89 which is connected by a crossed belt 40 with a pulley 41 onthe drive shaft 42 of the conveyer 29 whereby the latter is .driven inthe proper direction to carry the husked ears from the husking `rollersto a suitable receptacle. The conveyers 7 are driven by a belt 43passing over pulleys 44 on the shaft 45 thereof, and over a pulley 46 onthe shaft 81. Instead of the belt gearing as herein described sprocketwheels and chains may be employed.

The operation of the apparatus will be understood from the foregoingdescription, but it may be summarized as follows:

The stalks are placed on tlie table 6 with snapping and their butt-endstoward th husking rollers, and they are fed in this position to saidrollers by the conveyer 7 and the belt 15. The portion 18 of the rollerssnap off the ears and they are carried down singly to the plain portion20 and the spiked portion 19 of the rollers by the belt 15. The fingers15a of the belt force the ears against the spikes 'and insure theremoval of the husks. The object of the plain portion of the rollers isto prevent the corn from being shelled by the pressure of the belt 15.The husked ears drop on the conveyer 29 and are carried away. The huskspass between. the rollers and drop on the conveyer 30 to be carriedaway. The stalks as they issue from the rollers are chopped up by thecutter 27 and drop on the conveyer 80. 1f the husks have a tendency towrap they are removed by the teeth 28at and 28C as hereinbeforedescribed.

The apparatus herein described can be driven from any suitable source ofpower applied to the main drive-shaft 26. It is simple in construction,can be cheaply built, and it effectually serves the purpose for whichitis intended.
